ET takes you to the Hollywood premiere of the cinematic IMAX sea journey 'Under the Sea 3D,' and Jim Carrey, the narrator of the film, tells us how he made the filmmakers' job more challenging!

"I inject a lot of humor into it, and they take most of it out," Jim tells ET about bringing his own style to the film. "That's the challenge for them, take all the trash out."

'Under the Sea 3D,' opening in theaters February 13, gives moviegoers a giant and vivid look at diverse coastal regions in Southern Australia, New Guinea and the Indo-Pacific. The film also examines the impact of global warming on the oceans.
